Had a question about these. I can't remember exactly where, but I've read a couple of times that these units do not need to use traditional shear pins due to their over sized auger gearboxes. I saw one in the store last week and they appear to have some sort of shear pins...or is it just 2 solid bolts? Does anyone have one of the 826-828 series etc. that could she some light on my question?

Thanks.
